ATP World Tour reported that the superstar defeated Mikhail Youzhny in the finals in three sets:

Federer needed to win four matches to earn the title, only two of which he won in straight sets. Tommy Haas also forced him to a decisive third set in the semifinals.

Although he has struggled overall this season, this victory continued an impressive career for the Swiss player at Halle, according to Tennis Connected:

Considering his overall success throughout his years, it is quite surprising to see it take so long for Federer to get his first win of the year. However, the surface played a big part in the victory.

Federer took to Twitter to celebrate his victory:

The tournament in Germany is the first grass-court event of the season. It follows Roland Garros, which is the culmination of the clay-court season, and it is the first lead-up to Wimbledon.

There is no denying that grass is Federer's favorite surface. He owns a .873 career winning percentage and has won a number of titles in big and small tournaments (via ATP World Tour).

While Rafael Nadal is coming off a fantastic performance at the French Open and Novak Djokovic is still No. 1 in the world, it is tough to bet against Federer at the next Grand Slam. He has won at Wimbledon seven times, including last season, and proved at Halle that he is still solid with his finesse game on grass.

Despite an up-and-down season to this point, the Swiss veteran can clearly still get it done at the age of 31.
